Explanation:

<em>Given Data:</em>

mass = 80kg

acceleration = 4 ms

force = 800N

<em>Find out:</em>

friction = ?

<em>Formula</em><em>:</em>

F-friction = weight - f-net

<em>Solution:</em>

weight = (80)(10)

           = 800 N

F-net = ma =(80)(4) = 320N

F-friction = weight - F-net

               =800 N - 320N

               =480N

<em>Answer</em> :

Friction = 480 N
